Hello, I've noticed a crash in NSE (on linux, 64bits). A bug leads to a segfault at the end of the execution, after a failed pcap_open() call. I can reproduce reliably with (as root): # ./nmap --script pcap_crash -p12345 127.0.0.1 The reproducer is attached, as well as the call stack. I've tracked it a bit and figured out that in nsock_iod.c:254, mp->pcap_device is set to 0x4 but lack time for further investigations today. If I set more ports or change the debug level, it happens that the bug isn't triggered. HTH Let me know if I can provide more information. Regards. -- Henri
